The discovery of the first hot jupiter 51 Peg b
[1]} was a surprise for the astronomical
community because our expectations for exoplanetary systems
were based on the Solar system and it lacks an analogue of
giant gas planets that move around their host stars on orbits
tighter than that of Mercury. Later we discovered that the
Solar system does not have representatives of another class of
planets either – the so-called super-Earths or mini-Neptunes,
reported by [2]} and
[3]}, among others.
